Description
Technical field
The present invention relates to field of water quality detection, more particularly, to the full-automatic titration type of one
Test machine and full-automatic titration method thereof.
Background technology
The every field such as commercial production, food processing, medicine and resident living, it is right all to be unable to do without
Water carries out various process, and during water processes, an important link is water quality detection.At present, water quality
Detection mainly has three kinds of methods: the first is the side that traditional employing manually carries out medicament titration
Method, the second is to use the equipment such as various photoelectric sensors to detect water quality in real time, the 3rd
Plant is to use various sensors and dosing pump to detect water quality.
The first detection method, the advantage of i.e. artificial medicament titration method be testing result true,
Reliably；Shortcoming is, this method needs substantial amounts of professional round-the-clockly, carry out continually
Manual inspection, sampling work simultaneously there may be various danger.Cost of labor is high, work danger
Etc. defect so that the range of the first detection method is more and more less.
The second detection method, i.e. uses various sensor to detect water quality in real time, this
The advantage of detection method is the reduction of artificial use, reduces testing cost；Shortcoming is, uses
The detection equipment of sensor is easily polluted by the impurity in water sample, causes and damages and numerical value misalignment
Problem.
The third detection method, i.e. utilizes various sensor and dosing pump automatically to chemically examine.Its
The chemical examination of middle titration type includes two important steps: terminal identification in procedure and titer
The metering of dripping quantity.Wherein: the terminal identification in procedure, used identification face in the past
The Tansducer For Color Distiguishing of color, these Tansducer For Color Distiguishings titration procedure in color not
Become so that the sedimentary lab work being produced as terminal then cannot use.It addition, it is the most right
Instill instillation and the metering of infusion volume of titer, generally use precision metering pump or peristaltic pump,
Titer is pumped directly in water sample.The defect of this metering method is: first, from equipment,
The cost of precision metering pump is the highest；Second, from metering method, precision metering pump is dosing pump
The variable quantity of internal cavity represents the volume pumping out liquid, and peristaltic pump is metering wriggling round
The dynamic volume in the rolled pump line of angle represents the volume pumped out, so being easily subject to gas
The factor impact of bubble, pump line deformation etc.；3rd, transfusion catheter can only directly be inserted by this method
Entering in the water sample of chemical examination, this has resulted in the medicament at conduit outlet and the phase between chemical examination water sample
Pollute mutually, and pump can produce other error link between water sample.So, said method because
Detection error can not be caused to the amount of reagent in water sample by metered application exactly, and have the biggest

In putting 2.Such as, the quantity of multiple formulation reservoir 1 is identical with the quantity of multiple medicament drip nozzles,
And each in multiple formulation reservoir respectively with corresponding in multiple medicament drip nozzles
Individual it is connected.Multiple medicament drip nozzles include into medicine mouth 211 and medicine discharging nozzle 212, as shown in Figure 2.
Entering medicine mouth 211 to be connected with formulation reservoir 1 by medicament conduit, medicine discharging nozzle 212 is towards dripping
Determine the inside of device 2, internal for medicament being exported to titration appratus 2.
Level electrode 213, for detecting the liquid level within titration appratus 2, will detect number
According to being sent to control system 5, thus control the carrying out of titration operation according to the height of liquid level.
Medicament drop detector 214 is for the lower speed dripping the medicament dripped for 212 times from medicine discharging nozzle
Degree, through the time Δ t needed for the horizontal line region that medicament drop detector 214 is formed and
The number that drips of the medicament drop of lower detects, and testing result is sent to control system 5, from
And it is precisely calculated the total amount of the medicament that medicament titration process is used.
Water sample water inlet pipe 215 is used for connecting water sample water inlet 3 and titration appratus 2, and water sample is defeated
Enter to titration appratus 2 internal.Meanwhile, the medicine discharging nozzle 212 of medicament drip nozzle, level electrode 213,
Water sample water inlet pipe 215 and medicament drop detector 214 be arranged at upper cover 21 towards titration
Stretch out on a side within device 2 and inside titration appratus, be contained in titration appratus
The inside of 2, thus complete the detection to drop.In the inside of titration appratus 2, medicine discharging nozzle 212
Lower end be positioned at the upside of lower end of medicament drop detector 214, medicament drop detector 214
Lower end be positioned at the upside of lower end of level electrode 213, in titration process, level electrode
213 with the fluid level contacts of water sample, and control the liquid level of water sample in titration appratus 2.And go out
Medicine mouth 212 does not contacts with the liquid level of water sample with medicament drop detector 214, thus avoid right
The contact of medicine discharging nozzle 212 is polluted.
The upper surface open of overflow launder 22, lower surface are provided with overflow launder discharge outlet 221.Overflow
